' Application tiled May 26, 1882. (No model.)

To all uhom t't may concern Be it known that I, BENJAMIN C. VANDU- ZEN,of the city of' Cincinnati, in the county ot'Hamilton and State of Ohio,have inventi ed certain new and useful Improvements in Pumps, of whichthe following is a specitication.

My invention relates to that class of pumps known as double-actingforce-pumps, and ro has reference in general, tirst, to the constructionof the standard and of the base, and, secondly, to the construction andarrangement ot' the pump cylinders and valves, to enable the variousvalves to be readily removed from the x5 well for examination, repairs,and replacement. The various features of my invention will be obviousfroml the following description and the drawings, in which latter-Figure 1 is an elevation, partly in section, zo of a pumpembodying theprinciples of my invention. Fig. 2 is an elevation of the body of thepump, taken on a plane at right angles to Fig. 1, the base or bed pieceat the lower portion of the standard being shown in section. Fig. 3 is asectional View taken at the line l 1 of Fig. l. Figs. 4, 5, 6, and 7 areenlarged sectional views taken respectively at the line 2 2, 3 3, 4 4,and 5 5. Fig. 8 is an enlarged view of acentral vertical transversesection ofthe lower valve and its connections.

A indicates the standard of the pump,which is made of metal, andpreferably cast in one piece, and may be ornaniented to suit the taste eof the manufacturer. The upper end of this 3 5 standard is provided withthe brackets or ears a, between which the handle A' is pivoted. Near themiddle of the body is a globular enlargement, a', from which projectsthe spout A2. j The interior of this globular enlargement 4ocommunicates with the spout, but is separated from the interior of theupper part of the standard (which is preferably made hollow for the sakeotlightness) by a partition, so that the water cannot extend up in thestandard beyoud the enlargement a. The interior of the body is providedat a point ljust below the enlargement a with an interior ange, intowhich is screwed the upper end of the dischargepipe water.

B in such a manner that the water passes through the discharge-pipe andinto the enlargementaand directly out through the spout. The lower endof the body has a circular tapered foot or extension, Bf, which, whenthe pump is in position,.ts into a circular cup, b, formed in the baseC, and is firmly held therein. The taperon the standard of the pump` andthe reverse taper on the cup allowthe standard to be rmly wedged to thebase, and, as a precautionary means for preventing the standard fromworkin g loose from the bedpiece C, the bolts b are employed, passingthrough the bottom of said cup and through the bottom of said foot, asshown in Fig. 2. The base of the standard above the taper is providedwith a ange, b2, which overlaps and protects the edges ofthe cup. Thejoint between the bed-piece is thus elevated above the curb, and is outot' the way ot' snow and ice and The bolts b', being in the positionalready mentioned,are hid,and thebolt-holesaze in a position that norain and none of the water or other liquid coming from the spout orspilt from any vessel placed over or upon the curb or running down thebodyAof the pump can pass through them. This base, besides the cup b, isprovided withl an opening, D, through which certain ofthe parts beloware lifted when they are removed from the well, and the openingD isprovided with a cover, d, through which'the pump-rod D' passes. The baseC is provided with a surrounding Hange, C, by which it is secured tothel curb. This extension of the base is elevated for the same purposesfor which the rst-mentioned part of the base is elevated, and alsoeffectively braces the stand.- ard from lateral deflection andcontributes to firmlysecure the standard in position.

The discharge-pipe B passes down from its connection at the enlargementa through the body and the base C into the well, and to the lower end ofsaid discharge-pipe is connected the larger cylinder E, the pipe B beingscrewed into the projection e extending from the side ot' the cylinder,the projection being braced and strengthened by a web, e. Through thisprojection @passes the condnit'way E,by which the cylinder Ecommunicates with the discharge-pipe B. The cylinder E extends a shortdistance above the projection c, and its upper end is provided with aHaring mouth larger than the diameter of the cylinder, and into thedaring mouthts the upper and smaller cylinder, F. Near the center ofthis cylinder F is a surrounding collar, f, around whose periphery is apacking-ring, g, of elastic-material. This collar tits into the flaringmouth of the cylinder E, and the packing g forms a tight joint betweenthe two cylinders. lhe cylinder F, whose outer diameter is less than theinner diameter of' the cylinder E, extends down into said last-namedcylinder to a point just above the passage E', and the lower end ofthecylinder F is provided with an open flange or a number (preferablythree) ot' lugs, g, which tit against the inner face of the cylinder E,and by this means the cylinder F has two bearings within the cylinder E,and is thus held more firmly in position and in line with cylinder E.Theinterior ofthe cylinders being smooth and usually lined withporcelain or other glazing substance, the packing g forms aperfectly-tight joint between the inner face of the cylinder E andthecylinder F. The cylinder F is provdedwith a lateral projection, Gr,which isprovided with apassa ge-way, which terminates in an opening, h,passing through the collar f and communicating with the airspace Sbetween the cylinders.l Into the upper side of this hollow projection Gis screwed the lower end of the pipe H, which serves as an air chamber,and also as a rod for holding the cylinder F Iirmly in position withrelation to the cylinder E, and as a support for the clamps for guidingthe actuating-rod D, and as 'means for withdrawing the upper cylinder,F. The bottom of the cup b in the base G is provided with a lug orprojection, i, through which passes a set-screw, I, which latter may becaused tobear against the upper end ofthe pipe H. The'set-screw thusholds this pipe E, and through the intermediate agency ot' said pipe Hholds the cylinder F in position.

The cylinders F and E are located directly under the opening D in thebase C, and in these cylinders are located the plungers'J J', connectedto the pumprod D. These plungers are connected to each other and to thepump-rod by means of a bolt or rod, j, said rod being connected to thepump-rod and passing through a tube, cage, or frame-work, j', andfinally through the .lower plunger, J, a nut being screwed onto the endof the rod, by which means the two plungers are united. The lowerplunger consists of two metal plates or disks, K, each provided with aseries ot' openings, k, as shown in Fie. 6, a ring, L, ofleatherorothertlexible material,being clam ped between the two disks,the outer edge of the leather or tlexible material being turned up, asshown in Fig. 1, to form the packing for the piston. Above the disks Kis a circular iiexible valve, M, which permits the water to dow upwardthrough the openings r, but prevents any backward dow of water. I

1n the bottom ot' the cylinder E is placed a i =cylinder Ewhen it isdesired to examine or repair or replace it. The lower end ofthe pump-rodj is provided, as shown, with a screwthread. When desired, this end of'the pumprod j may have the female screw, and the arch or projection N2have a screw-threaded stud or teat, the thread of' which stud or teat,when the rod j is lowered, shall engage the female screw ot' the rodj,or the nut connected therewith, when thelatteris properlyturned. Whenthis valve N is to be removed the pump-rod D is disconnected from thehandle A. The pis.- tous with rody will then drop down until the end mot' the rod j enters the hole nin the ari-h N2, and by turning thepump-rod this end is screwed into said hole, and the ring N, is thusattached to the pump-rod, and may be lifted from the well with thepistons.

The lower end ot' the cylinder E is shaped as shown in Fig. l, beingsomewhat contracted, as shown at 1t, and into this contracted portionlits the ring N, to which the valve N is connected, an elastic packing,R', being interposed between the ring N and the inner face of thecontracted portion of the cylinder E. The shoulder between thecontracted `portion It and the remainder ofthe cylinder Eis, as shown att, rounded, and below this shoulder is a straight portion, t. Thelowerend or IOC margin ofthe ring N is also preferably rounded, and thepacking R,iitting into an annular chamber around the outer face ofthering, is shaped to'it the contracted portion R ot the cylinder.Preferably, instead of the packing R being so shaped, the constructionof the ring .N and ot' the packing R is as shown in the drawings viz.,the periphery of the annular recess S in the extension N of the valve ismade to correspond in shape with the interior shape of thecontracted'portion R of the cylinder. An elastic ring ot' packing, ofthe same and proper thickness throughout, is then placed in said recess,and the packing will conform to the shape of said periphery. \Vhen thering N and packing 1t are constructed in either of the formshereinbefore mentioned the ring is without ditculty guided into its seatat the bottom of the cylinder, a-nd the packing R forms aperfectly-tight joint.

An adjustable bracket, P, is connected to the pipe H, whichbracket formsa steadyingsupport for the pumprod,which passes through vthe free end ofsaid bracket, as shown in Fig.

IIO

1. This bracket consists ot two halves, p p', the inner face of eachofwhich, near the end which forms the support for the pump-rod, isprovided with a lug, q, and abolt, Q. Thelatter, passing through bothot' said halvesp p', causes them to firmly clamp the pipe H. the lugs gpreventing the pump-rod from also being clamped. This adjustable bracketmay be raised or lowered and secured in the desired position on the pipeH. Instead of being clamped on the pipe H, the bracket may be clamped tothe discharge-pipe B, and will necessarily/'be `clamped to thelast-named pipe when the pipe H is o1nitted,as will sometimes be thecase.

The upper cylinder, F, extending, as described, for some distance intothe upper end ofthe cylinder E,and being provided with the collarj', anair chamber or space, S, is formed around the lower end of thecylinderand the pipe H communicating with 4this air-space, a doubleairchamber is formed.

If desired, a solid rod may be substituted for the pipe H, and in thisevent the space around the lower end of the cylinder F will serve as anair-chamber and produce an uninterrupted dow of water from the pump.

When desired, the langef and its packing gare to be located on thecylinder F at a point nearer the upper end of said cylinder than isshown in the drawings, in which event the airchamber S will becorrespondingly enlarged.

When 'it is desired for any cause to remove the pistons and valves fromthe well the pumprod D' is disconnected from the pump-handle and isallowed to drop down, and the end m of the rodj is screwed into the holea in the arch N2 of the ring N', after which the plate or cover d isremoved and the set-bolt I unscrewed. The cylinder F, together with thepistons and valves and rod H, may now all be lifted from the well by thepump-rod, and may all be returned in a manner and order the reverse ofthose just described.

When the pump is in operation water is drawn into the cylinder E throughthe suctionpipe O, and the water so drawn up'is prevented from returningby the valve N. As the pistons are depressed the water passes up throughthe piston J', and as the pistons are again raised part of the water isforced into the cylinder F and part out through the dischargepipe B, theair-chamber SH producing a steady ow of water. When the pistons againdescend the'water is forced from the cylinder F out through thedischarge-pipe.

Certain features of my invention are applicable, by a few obviousmechanical changes, to pumps in which one cylinder only is employed. Oneor more of the various features of my invention may be employed alone ortogether, or in connection with pumps of construction other than thatherein described, so far as the same may be applicable.
